Average China-guy and Tony have fairly similar views on international trade issues – allow China to peg / float the currency however it wants, remove tariffs on lots of things… Which is why it came as such as surprise when someone mentioned “Harbin’s local medicine protection tariffs.” Huh-wha? I must have misheard, so I asked for clarification: additional taxes are often selectively applied on the sale pharmaceutical products [in Harbin] not made by Harbin Pharmaceutical Group, justified for purposes of ‘quality control’? (Officials here can more easily monitor the output of HPG; can’t be sure of that trashy herbal stuff produced in Shanghai – so go the anecdotes).
There’s definitely more to the story locally, and I plan to investigate. From what I can deduce so far, it’s linked to tax codes such that local governments can apply the highest tax rates to locally owned enterprises – thus the strong incentive to have such enterprises also feature the highest profit margins.
From its rhetoric, the central government strongly opposes these sorts of policies – insofar as they are related to local corruption:
… the local governments rely on local industries for tax revenue. It is thus conjectured that the local governments want to protect industries that have high tax margins… due to the lack of rule of law, even profits of privately owned enterprises are subject to some degree of expropriation, in the form of ad hoc taxes and fees, by the local governments…
That comes from Local Protectionism and Regional Specialization: Evidence from China’s Industries (Bai et al. 2003, SSRN here).
Data is always a problem; I’ve spent some time Baidu’ing for 地方保护主义 (‘local protection belief’) and come up with very little. This paper ( ”Regional Protectionism in China: Direct Micro Evidence,” SSRN here) utilizes survey results, and finds that regional protectionism has been decreasing over time. They conclude:
… Especially worrisome is that poor provinces such as Yunnan, Guizhou and Shaanxi experienced the highest level of regional protectionism… Third, the past two decades have witnessed a declining trend in regional protectionism, and the decline was gradual over time. This runs counter to some of the recent findings that suggest increasing segregation in domestic markets. Fourth, the gains from removing regional protectionism are significant. For instance, the average increase in revenue for the worst sufferers of regional protectionism would increase revenue by 9.1%, while the mildest sufferer would increase by 3.5%…
Fascinating. Further investigation required. If good data is available, examining regional impacts of protectionism could potentially remove biases inherent in examining cross country differences (where it’s very difficult to find representative variables for ’soft institutions.’) That being said, similar biases certainly exist within China, but are probably not as pervasive as those found internationally.
